BACKGROUND OF THE INVENTION 1. Field of the invention

The present disclosure relates to a control box and a display device including the same.

2. Description of the Related Art

With the advent of the information society, various demands for display devices are increasing. Various display devices, such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, electroluminescent display (ELD) devices, vacuum fluorescent display (VFD) devices, and organic light-emitting diode (OLED) devices, have been recently studied and used in response to various demands for display devices.

Thereamong, a display device using an organic light-emitting diode (OLED) is advantageous in that it has better luminance characteristics and viewing angle characteristics than a liquid crystal display device, and has an ultra-thin profile because it does not require a backlight unit, unlike the liquid crystal display device.

A control box may be positioned so as to be spaced apart from a display device and adjacent to a user so as to be used by the user. The control box may provide various pieces of information to the display device. For example, the control box may be an AV box. The control box may exchange information with a display head, which is provided with a display panel displaying an image, in a wired/wireless manner.

Recently, various studies have been conducted on the connectivity of such a display device.

The power supply PSU may be fixed to the first plate 210, and may be spaced apart from the second plate 220. The power supply PSU may be located closer to the first plate 210 than to the second plate 220. Accordingly, the heat generated from the power supply PSU may be transferred to the first plate 210 to be dissipated thereby, and may also be removed in an air-cooling manner by air flowing through the space between the second plate 220 and the power supply PSU.

A main board MB may be disposed between the second plate 220 and the third plate 230. The main board MB may be fixed to the second plate 220, and may be spaced apart from the third plate 230. The main board MB may be located closer to the second plate 220 than to the third plate 230. The main board MB may generate a larger amount of heat than the power supply PSU.

The rotary plate 203 may be rotatably mounted to the third plate 230. The transceiver 250 may be located between the rotary plate 203 and the third plate 230. The transceiver 250 may rotate together with the rotary plate 203. Further, the antennas 251 and 252 may pivot together with the dial 205.

The bottom part 2535 may be spaced apart from the top part 2532 so as to be opposite the top part 2532. For example, the front part 2531, the rear part 2536, the top part 2532, and the bottom part 2535 may together form a hollow rectangular pillar.

The front part 2531, the rear part 2536, the top part 2532, and the bottom part 2535 may be referred to as sink boxes 2531, 2532, 2535 and 2536. The thicknesses T1, T2, T5 and T6 of the front part 2531, the rear part 2536, the top part 2532, and the bottom part 2535 may be substantially the same as each other.

The first fin 2533 may be disposed between the top part 2532 and the bottom part 2535 so as to be parallel to the same, and may interconnect the front part 2531 and the rear part 2536. The second fin 2534 may be disposed between the first fin 2533 and the bottom part 2535 so as to be parallel to the same, and may interconnect the front part 2531 and the rear part 2536.

Each of the thicknesses T1, T2, T5 and T6 of the sink boxes 2531, 2532, 2535 and 2536 may be greater than the thickness T3 of the first fin 2533 and/or the thickness T4 of the second fin 2534. Accordingly, the heat dissipation effect of the heat sink 253 may be improved. Although the heat sink 253 is described as including two fins 2533 and 2534, the number of fins is not limited to two.

When the rotary plate 203 rotates, the rotational angle thereof may be limited by contact of the rib 2033 with the first stopper 237 or the second stopper 239. For example, the rotational angle may be 180 degrees. A first cushion 237C may be fixed to the first stopper 237, and the rib 2033 may come into contact with the first cushion 237C. A second cushion 239C may be fixed to the second stopper 239, and the rib 2033 may come into contact with the second cushion 239C.

The shock absorber 241 may include a hollow flow passage 241V. The third plate 230 may have therein an opening 230V corresponding to the flow passage 241V in the shock absorber 241. The inlet 243 of the fan 240 may communicate with the opening 230V in the third plate 230 and the flow passage 241V in the shock absorber 241. The housing 242 may have an open area defining the outlet 244 of the fan 240.

The heat generated in the region under the third plate 230 may flow to the outlet 244 of the housing 242 via the opening 230V in the third plate 230, the flow passage 241V in the shock absorber 241, and the inlet 243 of the housing 242. The upper surface of the housing 242 may be spaced apart from the upper plate 2032 of the rotary plate 203. A gap G may be formed between the upper surface of the housing 242 and the upper plate 2032 of the rotary plate 203. An airflow path may be created between the upper surface of the housing 242 and the upper plate 2032 of the rotary plate 203 due to the pressure difference generated by the strong discharge of air through the outlet 244 of the fan 240.

A discharge guide 260 may be disposed on the outer periphery of the outlet 244 of the fan 240. The discharge guide 260 may include a first part 261, a second part 262, and a third part 263. The outlet 244 of the fan 240 may have an elongated rectangular shape. The first part 261 may extend along the long edge of the outlet 244 of the fan 240. The second part 262 may be bent from one end of the first part 261, and may extend along one short edge of the outlet 244 of the fan 240. The third part 263 may be bent from the opposite end of the first part 261, and may extend along the opposite short edge of the outlet 244 of the fan 240. Accordingly, it may be possible to prevent the air discharged from the outlet 244 of the fan 240 from flowing reversely.

Referring to FIGS. 19 and 20, as described above, the case 201 may further have the third introduction hole 208 formed therein. The third introduction hole 208 may be formed in the lower surface of the case 201. External air introduced into the case 201 through the first introduction hole 202, the second introduction hole 204, and/or the third introduction hole 208 may absorb heat generated from the power supply PSU and/or the main board MB, and may be forcibly discharged to the outside of the case 201 through the discharge hole 206 by the fan 240.

External air introduced into the case 201 through the first introduction hole 202, the second introduction hole 204, and/or the third introduction hole 208 may be passed through the heat sink 253 (refer to FIG. 10) by the cooling fan 257 of the transceiver 250, and may be forcibly discharged to the outside of the case 201 through the discharge hole 206 by the fan 240.

The main board MB or the transceiver 250 may be a heat source, the temperature of which is higher than that of the power supply PSU. Therefore, the heat generated from the main board MB may be removed in a forcible air-cooling manner by the fan 240, and the heat generated from the transceiver 250 may be removed in a forcible air-cooling manner by the cooling fan 257.
